To all whom it may concern:

Be it known that we, Go'r'rnon FUEGEL a nd HERMAN SCHMID, who were formerly subjects of the German Emperor, but who have severally renounced all allegiance to Said potentate and declared our intentions of becoming citizens of the United States residing in Brooklyn, and State of New York, have invented certain new and useful Improvements in Confor Shafts or Journals, oi which the following is a specification.

Our invention relates to an improved connection -for shafts or journals; particularly shafts or journals used for the'armatures of magnetos in electrical ignition systoms of internal combustion engines.

An object ofour invention is to provide a connection for the shaft or journal of the armature of an ignition magneto of such a nature that no shaft or journal rigid with the part of the magnetowhichis to be coupled thereto; and to devise a method whereby the efiicient union of the journal question maybe completely and quickly effected.

'Other objects of our invention will ap pear from the following description,{ taken in connection with the of our lnven- This disclosure, however, is explanatory only; and we reserve the right to make changes in the shape, Size and am rangement of the parts of the embodiments of our inventiofsactually shown, within the scope and spirit of our invention, to the full extent indicated b the general meanings of the terms in W ich the claims are expressed, and by variations in the wording of the same. g.

is a side view of a piece or sec tion for making a journal or poses of our invention;

Fig. 2 is an end view of said section; 1 Fig. 3 is an ture of the armature of a magneto to which the shaft or journal is to be united;

in the county of Kings theproper size and" provide the:

additional members, fit-e tings or the like will be required to make the,

or shaft with the part accompanying' drawinner face of to make the ends of theseshaft, show-' ing how the same s shaped for the pur-' end view of part of the struc- Fig.4 is a sectional view-showing said Shaft and said partas' they will appear. when made fast to eachother, and the;con-. 56 nect 10n is finished=;'-and Fig. 5 is a front view'of the samepart'o f" thearmature, s in modified connec t10n.' f

The same referenc ch same parts throughout.-

In the practice of our a cylindrical piece or section .acters ids pro ections at one end thereof; Such apne of metal is indicatedatl in the drawings; u

and is shown as havinga recess 2 imone extremity providedy by outtingafgroo ve, '1

straight across the samerjrlnth si way We i provide the section with two'terminal pro-. jections 3. a f' In, order to secure this piece of metal 1'. tovthe body of the-armature of a magnetm'j we prefectoj unite the same withthe con enser caslng which is usually joined to the" ole pieces of the armatnreaton'e" end of the atter. Such a casing is shown at 4 in Figs.- 3 and 4. It iscylindrical'and cup-shaped, and in the bottom thereof it has a pair of apertures5 of the sameshape as the projectlons 3. Each of theseapertures or openings will be enlarged somewhat'arou'nd the the bottom of the casing, by counter-boring or otherwise, as indicated in Fig. 4 by the numeral 6. To join the section 1 to the casing 4 we insert the terminal ,pro-

,. jections 3 into the openings 5' fromthe out-.

Side or outer face of the-bottom of'the casing mg, or by pressure otherwise ap J rejections engage t1ghtly--w1th the counterored .rims of'the open ngs 5. In

the casing 4 will be made pennanentiy rigid )Qwith each other; and when the casing 4'is .95

fiaflix'edto th thel-body with a ournal 'the-ca'smg 4 is1 applied, to provide for the,

epole pieces :of the armature A of the armature. will be provide or shaft at the end to which rotation of th bearingpfor the same.

e do not believe that such an armature", i N

or any other part of the magneto, except the easing 4, need -be shown herein, for the J plied,

this waythe section 1 and e: armature in the adjacent reason that the structure'of the armature of 11o" tween the magnets which provide the.mag-

netic field. The oles are segment-shaped in cross section. or this purpose the rim of the casing i is provided with thickened portions on opposite sides, as indicated at 7 'm Fig. 3;.these thickened portlon-s also being'segment-shaped tocorrespond in outline with the ends-of the armature poles,.

and thus enabletheermature and the casing to be conveniently fitted together. The

29 thickened portion 7 may have-openings. 8

for screws or bolts to hold the armature and the casing fast to each other.

In the aboveniannei' weprovide a very efficient coniiectionforashaft or journal at one endef the armature of the magneto Without haying to use any extra members to secure the shaftffor joiil nal in place, and the Imethod is verysiilipleand can be easily followed with excellent results.

Insteadjof only two projectionson the end of the section 1 we may provide more than two as shown in Fig. "In this View the section .1 is shown as oined to the casin Ibyfour projections; and the casing is shown n as heving four openings 9 in its bottom.

The pro ections .in'the openings as they a 'nppenr after being expanded to engage the [td'uhMr-boied ends'of these openings are inc'dicat'ed-et 10. Of course the inside or" the to bottomof the casing is ground oii slightly in order make the sanieeniooth-aiter the Leveeeo BEST AVAILABLE COPY operation of joining the piece 1 to the casing is finished. Q

After connecting the section 1 to'the casing i, we may of course turn down the sec tion in a lathe to reduce its diameter, out threads thereon, or work it in any other manner as it may require.

The piece 1, while preferably cylindrical can in factihave almost any cross-sectional form and still be adapted to the purposes of our invention as above set forth.

Having described ourinvention what we believe to be new and desire to secure by Letters Patent of the United States is:

l. The combination. of a cup-shaped casing having openings in its bottom, said openings being counter-bored adjacent the inner face of said bottom, and a shaft provided with projections on one end, said projections entering said openings from the outer face of said bottom, and being expanded'to engage the counter-bored portions of said openings to secure the casing and shaft together.

2. The combination of a cup-shaped cas ing having thickened portions at its opposite sides, and having one or more openings in its bottom, sa1d 0pen1ngs belng counterbored adjacent the inner face of said bottom,

and a shaft provided with projections on the end thereof,-sa1d projections entering said openings fromthe outer face of said bottom, and being expanded to engage the. counter-bored portions of same to secure the casing and the shaft together. v In testimoi'ywhereof, we have signed our names to this specification-this 1st day of November 1918.
